The fourteen-year life story of a sealed terrarium is presented. (BB)

Presents a science activity to help students to explore the concept of primary productivity by growing lawn grass in the classroom. (HM)

Describes and details the construction of a land-water environment using an aquarium and variety of terrestrial and aquatic materials and organisms. Suggests activities such as identification of organisms, observation of predator-prey interactions, construction of food webs, and recognition of interdependence of biotic and abiotic factors. (CS)

Thirteen suggestions for student research projects are presented. Project topics include birds, fish, frogs or toads, insects, spiders, crustaceans, mammals, predators, and ecology. The teacher's role in managing student projects is discussed. A list of middle school textbook resources is provided. (KR)

Presented is a classroom activity designed to acquaint students with sampling techniques before going into the field. Using a one-inch quadrat, students sample a printed page and learn to collect and interpret their data. Performance objectives, preassessment, teaching strategies, postassessment, and illustrations are included. (MA)

Demonstrates the use of a proactive approach to aid teachers in the prevention of behavior or management problems during a class field trip. An outdoor field exercise using string to define each groups' study area and focus student attention is included. (ZWH)

Demonstrates how students can build a plankton net using common materials for environmental education. (LS)

Intended to aid teachers help students discover the concept of human beings interrelating and interdependent with their environment. A science activity used with sixth grade students involved in a functional recycling system for newspapers is described. The program grew into a community-wide project, incorporated with city council. (EB)

Presents methods for analyzing soil and water samples in this classroom. Includes a classroom diagram, a listing of suggested materials, and the procedures for a classroom simulated pond. Relates classroom activities to work at a natural pond. (MA)

Presents a mini-environment project as a valuable teaching tool for presenting ecology. The procedures for setting up a mini-desert in the classroom are presented as a model. Basic components of the mini-environment project are also included. (HM)

Describes activities with organisms from freshwater ponds and ditches. Several experiments involve predation, some involve habitat choices, and one addressees the role of sunlight in supporting plant-eating animals. (PR)

Uses models to illustrate the possible "migration route" of the sugar maple in response to predicted global climate change. Curriculum activities for students are provided that specifically address the sugar maple forests of the Great Lakes regions. (ZWH)

Describes a project in which students study plant life and the relationship of plants to one another in a meter quadrant. Information to be collected is edaphic data which is then graphed and interpretations made. (BR)

Describes a game for grades three-six designed to demonstrate the interdependence between living things and the physical factors of their environment. Although instructions (including preparing game cards) are provided related to a pond, the game adapts to other environments such as a field, woodland, or desert. (Author/JN)
